    Is my CPU hot?


    Long story short, I had to return an AMD 8350 due to a faulty memory controller. AMD fortunately sent me a replacement, but I'm wondering if it's running too hot - and am I reading the temps correctly in CUPID HWMonitor? I've now reinstalled this processor two times - as per below:

    (1) Upon the first install on this motherboard, the temps were waaaaay too hot. It was running up to 70 degrees C, in under 10 minutes while I was using Prime95 as a stress test... so turned off the computer and I reapplied thermal grease (OCZ Freeze), and added a second fan to the liquid cooler setup. One fan on each side of the radiator. I also turned off cool n quiet in the bios to maxamize the liquid cooling pump. The cooler is an Antec 620.

    (2) Running Prime95 for 20 minutes, I'm getting these numbers - are these reasonable, or do I have a problem, and am I interpreting the results correctly? ie) which one is the cpu socket vs. the actual cpu?



    Thanks.

    edit , I think I might have been wrong .just ran the program on mine and my temps are way less than yours ,sorry for the miss info

    no ,those are ok temps for you computer
    can see all the app that running ,but one could be video card chip. the amd fx one is the motherboard processor

    prime95 can over stress the cpu to push up the temps

    My opinion, Prime95 is overkill and can stress a system way over what any intense game can or what the system is designed to handle be it a desktop or laptop. I won't run it personally.

    when changing the cpu did you make sure it had the right amount of thermal past, not to much ,just a nice even thin coating is good

    On your version of HW Monitor you get only "Package" temperature, not by core. Package temp can go to 90c on that processor before shutdown, core temps should not go more than 62 -63c. CPUID HW Monitor - professional can show Core temps too. Take note that those processor "lie" about temps at idle but those are not too important anyway.

    Thanks everyone for the advice. I'm glad to hear that I'm not crazy again. I've was using prime95 as it accurately diagnosed a faulty AMD 8035 processor (issue with memory controller - it was fully troubleshooted elsewhere on this forum), and it's a decent stress-test. I just wanted to ensure that my new CPU was 100% a-ok

    Interestingly enough I let my computer sit idle for about 10 hours -- nothing was open except evernote -- and I was shocked to look at these temps.. why the wide variation up to 70c... can't make sense of it. Maybe, as you say Mike, there's a lie in the max value somehow.

    When I run IntelBurnTest (Heavy Mode) on my system the cores reach 78C !

    I can hardly believe your temps... unreal low. what do you have on the cpu, liquid nitrogen?

    Being near 80C with my 4770 at full load is quite fine to me, but something better than my Corsair H-60 would be a good move !

    There's thing called "Temperature offset" which is about 10c for late AMD processors and those programs may or may not calculate it in their measurement. It can make larger difference than room temperature change so it's not exact science. On those processors there is a pin (forgot now exact designation) that transmits that "Package " temp and it's from the base of the processor. That one is usually higher than "Core temp" whose sensor is on processor's die for each physical core. That one is more important than package temp because it shows temps at contact surface with cooler. Difference between those two temperatures triggers core or whole processor shutdown if reaches some set temperature set by MFG.
    Most MB manufacturers have their own temperature, fan speed etc. programs and may be more accurate.
    Just looking at Fan speeds and looks like your pump may not be running at full speed, I believe it's FANN1. Can you check with cooler's manufacturer what it's full speed should be ?
